As Brazil gears up for presidential elections starting on 6 October, BBC Brasil's Paulo Cabral has completed a journey through remote mountains, arid countryside and deep jungle to find out what 21st Century politics mean in the Brazil that normally goes unreported.

Bororé Island is a district in the southern part of the city of São Paulo.

Some people will have to travel two hours by bus and ferry to vote

Bororé is not quite an island, but 90% of it is surrounded by the waters of the Billings Reservoir.

One precarious, barely used road is the only access by land.

Two ferries link the district to the cities of São Paulo and São Bernardo do Campo.

Not a single ballot box for the island's 3,000 or so residents will cross the waters.
